Mistake #3: Crooked or unsquare slots
The start-up torque of a joiner can cause it to lurch when powered up. Resulting slots might be unsquare, as shown at top left.
Solution: Never make field cuts (in the interior of a workpiece) freehand. Instead, clamp a stop to your workpiece-right on the line for the bottom of the mating board-and use that as a reference point for the joiner, as shown at bottom left. To counteract the lurching, start the motor and then line up the joiner with the mark before plunging to make the cut.
